wooomueven CHAIR-TIP.

The Schedule referred to in these Lettera' Patentvand making part of the same. u

To alll w'honf it may concern Be it` known that I, EDWARD CooGAN, of the city and county of Washingtomin the District of Columbia', fhave invented a.- certain Improvement in Elastic or Flexible Chair-Tips; and I do hereby declare that the .following-is a full, clear,

and exact description thereof, reference being had to the annexed drawings, making part of this specilication, in which- Figure 1- is a vertical central section of my improved chair-tip, and a portion of the leg of a chair.

Y Figure 2 is a perspective view of the tip, showing its construction.

Correspondingletters refer to corresponding parts in Vboth figures.

`Ghair-tips, as heretofore constructed, have been found fvto be objectionable on account of the`great difficulty there has been in inserting them into the cavity, and securing them therein. When they have been so constructed as to be capable of ready insertion, it has been foundnecessary to insert around them some kind of cement for the purpose of securing them in their positions, which operation causes much delay and great difficulty in removingl the-m when it becomes necessary in order that their places may be supplied with new ones, or that they may be placed in a new or another chair.

The present invention is intended to provide a remedy for the above-en umeratcd dilculties; and, to thisiend, A It consists in an elastic or liexible tip for chairs, tables, bedsteads, and other descriptions of furniture, which rest upon legs or posts, consisting of rubber, gutta-pereha, or other suitable elasticor flexible material, having upon its lower or outer end a globular or otherwise formed enlargement, upon which it and the article to which it is applied, rest, while that portion which enters the leg or post is in the' form'of a frustuin of an` inverted cone, with its apex or 'smallest portion joined to the globular portion, while its larger portion extends upward or out-ward for a distanceV s ufficient Vto enable it to pass into a cavity to be formed in the leg .or post, such upwardly or outwardlyprojecting part being 4made hollow or tubular fora portion of its length, so that, on inserting it into the cavity, it may be easily compressedy to the size of that pat which unites. it to the enlargement lupon its outer en A, in the drawings, refers to the enlargement upon the tips, A'- referringto that portion which enters the cavity formed in the leg or post of the furniture. This tip may be made of India rubber, gu't-tapercha,.or other suitable material, and is best when formed as shown in fig. 2 of the drawings, but it may, however, be square or rectangular in its general outline; in either case, that portion which enters the material of which' the post or leg is composed, is to be larger upon its upper end, or in that portion which first enters the cavity, and is to be provided with a recess or cavity, which shall extend forI some distance into the same, so that, ,when about to be inserted into the post or leg` of any piece of furniture, it may be compressed tothe dimensions of that portion which joius'the 'enlargement upon its outerend. This form ,of construction enablesv the operator to place the tip'iu any piece of furniture to which he wishes to apply it, by simply boring a hole. for the reception of the shank A.

The upper or outer end, although the largest, is easily compressed so as Ito enter the h'ole, when it may be forced in so as to cause the post to rest upon the enlarged portion, as shown in tig. l of the drawings.

Vthen the tip is in place, the tendency of its upper end to enlarge itself to its former dimensions, secures it from being drawn out by use, and retains it in position until it becomes necessary to remove it, when, by the application of the requisite amount of force, in a direct line with the post or leg, it may be easily withdrawn. B refers to a section of the leg of a chair, they con-v struction necessary.to adapt it for the reception of the tipbeng duly shown.

Having thus fully described my invention,

What I claim, and desire to secure by Letters Patent, is-' 1. An elastic or flexible tip for chairs and other kinds of furniture, having a globular lower o1"v outer end, from which projects a shank, A', in the form of an 'inverted truncated cone, hollow at its upper end, substantially as and for the purpose 'specied 2. In combination with the above,A the leg or post B, substantially as and for the purpose specified.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

EDWARD GOOGAN.
